Figure 2. T cells apoptosis in the liver allografts is B7-H1-dependent.
Liver and heart GICs from recipients of allogeneic liver and heart graft on day 6 after transplantation were isolated and staining with CD4, CD8 and Annexin V. Apoptosis of CD4+ and CD8+ T cell from liver allograft was greater than heart allograft and T cells from a liver allograft without B7-H1 expression showed no apoptosis. The GICs from 3 mice per group were pooled and the results are representative of two separate experiments.
